- Native (processing)
Native: Methodology for sharing code processing over a number of
CPU cores At some fundamental level, all
computers have a 'core ' which takes care of the primaryprocessing . Instructions, originally written in some high level language, finally get broken down intomachine code and executed.Java programming
In Java programming language,
nativeis a method-specific modifier. It must be noted that fields, classes and interfaces thus cannot be declared as native.Multiple cores
Recently, there has been a trend to add more cores to a system.In theory, the more cores a system has available to execute instructions, the more work gets done. It is not the case, however, that a two core system possesses twice the processing power of a single core system. The amount of improvement will depend on many factors - including available bandwidth and code efficiency.In this context, native refers to whether one core is independent of its neighbors.
Practical applications
Current (2006)
Intel quad-core technology can be viewed as a pair of dual core processors that happen to have been built onto the same substrate.Proposed (2007)AMD quad-core technology consists of 4 separate cores, which can operate with their own resources, independently of their neighbours.How much of an advantage native technology offers will be a hotly debated subject for some time to come.Is there a native advantage - or is it justmarketing terminology within a hair-splitting exercise ?For more info, try balancing http://multicore.amd.com/us-en/quadcore/ with http://www.intel.com/products/processor/core2quad/index.htm
